Integrated telescopic seatposts
Conventional dropper seatposts are heavy, elastic, and are clamped into the frame just as they were 120 years ago.
Eightpins takes a different approach: the seat post is not an additional part—it is part of the frame. With a larger diameter, less weight, and significantly higher stiffness, it ensures a precise, durable, and clean riding experience.
- Up to 258 mm stroke for maximum freedom of movement
- 33 mm diameter for the highest Stiffness
- Large-sized bearings for lasting reliability
- Fully serviceable and thus sustainable
- Clean design without external terminals or cables
- Height as simply adjust like a car seat
- To 99% of all driver sizes customizable
- Automatic travel adjustment to rider height
- Lower operating personnel. Less Friction.
- Up to 30 % less weight
Stiffshifter – Maximum precision for your UDH derailleur hanger
The Eightpins Stiffshifter is the next evolutionary step for bikes with UDH derailleur hangerModern derailleurs are longer, wider, and more exposed than ever before—and the UDH derailleur hanger is simply too weak for this. Even slight contact on the trail can lead to imprecise shifting or bent derailleur hangers.
This is exactly where the Stiffshifter comes in: it reinforces the connection between the frame, derailleur hanger, and rear derailleur, ensures more precise Shifting and reliably protects the entire system from deformation.
- Protects your UDH derailleur hanger
- Stabilizes modern derailleurs
- Prevents switching problems
- Massive stiffening through clever design
- Easy installation – big impact

As a trial rider, I need sufficient freedom of movement on the bike, which is why I appreciate a low saddle position. My riding style is "crazy playful," and thanks to Eightpins seatposts, I can live it up to the fullest. The ingenious lightness of the seatpost means that lowering it works even on difficult terrain.
Steep and technical terrain always require complete control. The lower the saddle, the more freedom of movement I have to master such challenges. On my adventures, I also need to be able to rely completely on my equipment. The Eightpins seatpost offers me both.
